We May Finally Have a Way to Detect Hawking Radiation Leaking From Black Holes

Posted by in categories: cosmology, quantum physics

O.o!


The epic collision between two neutron stars in 2017 really is the science gift that keeps on giving. As they merged, gravitational waves rippled out across the Universe; now reverberations from that event could confirm a decades-old hypothesis about black holes.

The Expanding Universe Might Not Depend On How You Measure It, But When

Posted by in category: cosmology

It’s been called the biggest conundrum in all of cosmology, and recent measurements just add to the confusion.

A new ‘Einstein’ equation suggests wormholes hold the key to quantum gravity

Posted by in categories: cosmology, information science, quantum physics

A new Einsteinian equation, ER=EPR, may be the clue physicists need to merge quantum mechanics with general relativity.

Quantum weirdness could allow a person-sized wormhole to last forever

Posted by in categories: cosmology, quantum physics

We were unsure if wormholes could exist long enough to allow a person through. Now calculations indicate they are extremely rare, but could last the age of the universe.

Did Scientists Finally Solve the Impossible Physics Riddle?

Posted by in categories: cosmology, physics

A theoretical physicist in England has won a prestigious award for her work on the theory of massive gravity, which could explain why gravity hasn’t constrained the rapid expansion of the universe. The $100,000 award honors the work of Claudia de Rham, who has worked for 10 years on a way to turn massive gravity theory into something measurable.

Cosmologists have puzzled for decades about how to marry gravity with the speed at which the universe is expanding. Gravity as we understand it would work to hold the universe together, not let it race apart from itself into eventual oblivion. Enter the counterpart to dark matter, dark energy, which is what scientists call whatever is pulling the universe apart.

New Theory Could Solve Universe’s Biggest Paradox

She is now hopeful that advances in gravitational wave astronomy will make it possible to test the predictions of massive gravity theory within the decade.

“It would be amazing if it was shown to be right,” De Rham told The Guardian. “That may or may not happen, but what will happen is that we’ll have a much better fundamental understanding of gravity and that’s just something so deep, it’s one of the big questions today.”
